So there I was getting ready to depart SPB, I hear someone call, "XXX turning base". I take a look down final, make a quick radio call, "Cessna bla bla bla departing RW15" then look again to make sure it's clear on final before proceeding onto the runway.
All of a sudden as I'm 1/4 way and still perpendicular to the centerline, I hear, "Excuuuuuse me, I'm on short final", and I see the person who made the earlier call finishing a very short final turn from base.
It was short enough that I doubted being able to depart safely so I gunned it across the runway to the opposite taxiway and gave her the runway.
I was surprised by how quickly she went from base to final and how close she was. With a high wing airplane, I had very little visibility of the base leg.
The question is, who is wrong here, if anyone, and what would have been the best procedure for either of us? As the pilot turning short base to short final, should she have been better off and more obligated to announce a go around? I did what I felt was safest but would have been stuck if the taxiway on the other side wasn't clear. I could have, perhaps, stayed put and told her to go around. Departing out in front of her just seemed too risky.
